CARL G. PRITCHARD, OF WARREN, OHIO, ASSIGNOR TO THE HARRIS AUTOMATIC PRESS COMPANY, OF NILES, OHIO, A CORPORATION OF OHIO.

DELIVERER FOR PRINTING-PRESSES.

Specification of Letters Patent.

Patented July 8, 191%).

To all 10/1/0112, it may concern:

Be it known that I, CARL G. PRITCIIARD, of l/Varren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Deliver-ers for Printing-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The primary object of this invention is to provide simple and highly eflicient means for discharging stock from a printing press.

And a further object is to provide a deliverer capable of being used in a restricted delivery space, and especially adaptable to multicolor printing presses handling sack tubes, card-board or other relatively stiff paper, rendering the use of complicated conveyers unnecessary and lessening the danger of smearing.

According to my invention each sheet or other article, as it leaves the impression cylinder, enters a guide from which it will be discharged in reverse order when its tail end is free of the press-cylinder.

In the accompanying drawings, Figure 1 is a view in side elevation. Fig. 2 is a front elevation. Fig. 3 is a diagrammatic view showing in dotted lines the various positions occupied by an article as it is being discharged from a press.

Referring to the drawings, 1 designates an impression cylinder; 2 the press frame; and 3 guideor take-oil wheels mounted on .a common shaft 4. 5 designates ordinary strippers which are shown in the term of fingers depending from a common rod 6 and extending at their lower ends toward the face of the impression cylinder.

To a cross rod 7 of the press frame are secured upper guides which are shown as being composed each of an inner member 8 and an outer member 9, said members being on substantially parallel lines with each other. They are shown set at a slight angle to a vertical plane passing through the longitudinal axis of the impression cylinder. but they may be set in any desired position. The inner members 8 are shown as overlapping the n per ends of strippers 5, while the outer mem ers 9 are carried downwardly beyond said strippers and terminate in outwardly curved portions as indicated at 10. 12 designates the lower guides which in com junction with the curved portions 10 of the outer members 9 form a guideway for the discharge of the stock. These guides 12 are shown as mounted on a cross-rod 13 and as extending at their inner ends up to shaft 4 which carries the take-0E wheels 3, while their outer ends are projected downwardly at an angle substantially parallel with the lower ends of the outer members 9 of the up er guides.

n practice the sheet printed upon-bagtubes, or relatively stiff sheets like cardboard-is stripped from the press cylinder in the usual way by strippers 5 and passes upwardly into the upper guides, which movement may be limited by adjustable steps 14. The tail of the sheet is swung past the inner ends of the lower guides 12, either mechanically or by momentum, and when free of the press-cylinder the sheet being without support will immediately fall from the upper guides, and by means of the lower guides 12, aided by the lower portions of the upper guide members 10, will be discharged onto a pile or any suitable receiver such as a lay-board 15, or onto a conveyer of any suitable construction. According to the means shown each sheet is reversed, that is, turned upside down, or inverted, being discharged with its printed side up, but it may be discharged in any desired direction after its travel in leaving the cylinder has been arrested and reversed.

Although I have shown fixed guides for directing the sheets in their reversed travel, any suitable means, such as rolls or endless tapes, may be employed to assist in delivering sheets to the desired point.

In the claims appended hereto I have used the word sheet as designating the article printed upon, but it will be understood that this term contemplates tubes, such as are used for forming paper bags, as well as any kind of sheet having sufficient inherent stiii'ness to insure the upward travel of its forward edge into the upper guides so that when its tail is 'free of the press-cylinder it will be discharged tail end rst.

I claim as my invention:

1. In combination with a printing press having a rotary cylinder and means for stripping sheets therefrom, means for controlling the movement of the sheet as it is stripped from the cylinder, and relatively fixed guidinggmeans cooperating. therewith for effecting discharge of the sheetin a reverse position.

21 In combination with a printing press having a rotary cylinder and means for stripping sheets the1'eiroiii-,;fixedguidesfor controlling the movement of the sheet as, it is stripped from the cylinder, and an in clined guide cooperating therewith for effecting discharge of the sheet in a reverse position.

3. In combination with a printing press having a: rotary cylinder and'mea-ns for stripping sheets: therefrom, means for ar resting rthe-i travel of the sheet as it'-is stripped fromthe cylinder, and an inclined guide cooperating therewith for effecting discharge of thesheet in: a reverse position.

.l. In combination with a printing press having azrotary cylinder and means-for stripping sheets therefrom, mea11s-*for're ceiving: and arresting thetravelof the sheet as it is stripped'fro'inthe cylinder and fr'om which it willpass byigravit y, and means for efiecting: discharge of the sheet in a reverse position.

5. In combination With a printing press having; a rotary cylinder and means-" for stripping sheets -therefrom,-means -for receiving each sheet as it is stripped from the cylinder and discharging'it tail end first, and.-- fixed guides for reversingthe position of the sheet as itzpassesfrom said receiving means.

6.- In combination with a printing press having arot'ary cylinder and means for stripping sheets therefrom, means for receiving each sheet in a substantially upright po sition as it isstripped from the cylinder'and fromwhichitwvill pass by gravity, tail end first, in a. contrary direction, and inclined guides cooperating therewith for efi'ecting discharge of the sheet in'a reverse position.

7. In combination with aprinting' press having a rotary cylinder and means for stripping sheets therefrom," guides into which each slieet is delivered from'th'e cylin-* der I and from which it w ill pass by gravity, and fixed cooperating the position of the sheet as it passes from said guides;

8$-In combination With' a printing press" cylinder and means for" hZLVIIIg a rotary guides for reversing strippingsheets therefrom, upper guides for receiving the advance end of each sheet and from which the sheet will pass when the tail of the sheet is free of the press cylinder, and guides for cooperating with the first mentioned guides for discharging the sheet, tail 9. In combination with a printing press having a rotary cylinder and means for stripping sheets therefrom, upper guides, set an angle, for receiving the forward end of each sheet, and'lower guides for discharging each sheet, tail end first, as it passes from said upper guides. Y

' 10. In combination With a printing press having a rotary cylinder and means for stripping" sheets therefrom, upper guides coniprisinginn'er and outer members, a stop carried by one of said members" for limiting the upward movenientof the 'for'ward"end of a sheetdischarged from saidpresscylinder, and lower" guidesbeneath said upper guides for discharging each sheet, tailend first, asit passes from said upper guides.

11. In combination with a" printing press having a rotary cylinder and -means for strippinga sheet therefroin, an upper sub stantially upright guide for receiving the sheet after it is stripped-,saidguide having inner and? outer vertical Walls, said outer wall extending a lower guide extending downward at' an angle to said upper guide.

12. In co nbination with a printing press havin a rotarycylinder and a stripperlad jacent' said cylinder,*an upper substantially upright guide for receiving a sheet after in is stripped, said guide liavinginner and outer vertical Walls, said inner wall overlapping said stripper, said outer wall e'x belo'w said' -inne'r' wall, and

tending below said inner wall and having anangular' extremity, and a lowr guide" extending downward atan anglefto saidu'pper guide and parallel with' -said angular'extre'mity.

In testimony whereof; I have signed'this specification in the presence o'f t'wo subscribing Witnesses.
